Organized by the Confederation of North, Central American and Caribbean Association Football (
CONCACAF) and Confederación Sudamericana de Fútbol (
CONMEBOL), the 1978 edition was played between March and April 1978. In the first leg, held in
La Bombonera in
Buenos Aires, Boca Juniors won 3–0. In the second leg, held in
Estadio Azteca in
Mexico City, América beat Boca Juniors 1–0. Despite Boca Juniors had a
goal difference of 3–1, it was not taken into account and a playoff match had to be played. Agreed by both clubs,[1] it was held in Estadio Azteca again, where América beat Boca Juniors 2–1 to win the series 4–2 on points, achieving their first Copa Interamericana title.[2][3]
